One Adapter, Every Resolution: Gated Low-Rank Adaptation for Remote Sensing VLMs
ScaleEarth is a fine-tuning framework that adapts remote sensing vision-language models to handle vastly different ground sampling distances (GSDs). It uses CS-HLoRA, which dynamically routes computation based on GSD as a continuous variable, allowing the model to smoothly transition between high and low resolutions. This makes the physical scale an active signal for better performance across various Earth science tasks.
